l SPECIFICATION forming part of Letters Patent No. 462,143, dated October 27, 1891.

Application iiletl November 3, 1890. Serial No. 370,199. (No model.) l

To o7/Z whom. it may concern:

Be it known that we, FRANQOIS X. LAM- BoLEY and ABRAHAM JAcoBsoN, of New York city, in the county and State of New York, have invented a new and Improved Button- Olasp, of which the following is a full, clear,

and exact description.

The object of our invention is to provide a practical button-clasp designed particularly for attaching buttons to seal-skin garments, though it may be used for other purposes.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate correspondingr parts in all the views.

Figure l is a front elevation of the clasp shown applied to a piece of fabric, the button being` removed from the spring and main plate. Fig. 2 is a similar view showing the method of closing and opening the clasp. Fig. 3 is a sectional elevation on line a: @c of Fig. l. Fig. at lis a side elevation showing the clasp open. Fig. 5 is a front elevation of the button and button-loop, and Fig. 6 is a plan view of the washer.

The iuventionwill first be described in connection with the accompanying drawings, and then pointed out in the claims.

The button A is mounted on a spring' a and held thereto by suitable fastenings. Attached to the free end of this spring is also a plate b, which is turned to form a catch b;

but the spring and plate or the spring and catch might be of a single piece of metal, if desired. The said spring is substantially U- shaped and acts both as a straight and as a torsion spring, the former to open the clasp and the latter to engage the catch b with the stud c bya lateral action or movement. The spring is made of two thin plates a e201? steel, placed flat together and secured so that the outer plate re-enforces the inner and prevents either from breaking and enables the spring, as a whole, to be made very delicate.

The stud c forms the button to hold the Vbraid B, and is provided with the threaded the outer end of the said plate d2, which, when the screw d is turned down, is embedded in the fabric and prevents the clasp from turning, and to still further guard against turning We may form a notch m in the washer m., into which the said projection or lip f will press the fabric when the screwA is turned tightly into the screw-socket d.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. A button provided with a clasp consistin a U-shaped spring, the inner member of which on its inner face is provided With a tubular loop-engaging post having a'flange or lip, an inward-projecting catch on the outer member adapted to be sprung under said lip by a torsional strain on the spring, and a fastening screw or pin to pass through the garment or fabric into said tubular post to secure the clasp in place, substantially as set forth.

Q. A butto'n provided with a clasp consisting in a U -shaped spring formed of two superposed thin plates a CL2, secured together, a plate di, secured to the inner member of the spring andV having on its inner face a tubular iuternally-threaded post c, having a flange or lip at its end, a securing-screw d to'pass through the fabric or garment into the said post from the outside, and a plate b, secured to the outer member of the spring and having an inward-turned catch b on its outer end to engage the post-iiange laterally by a torsional strain on the spring, substantially as set forth.

3. A button provided with a clasp consisting in the U-shaped spring having the extremity of its inner member bent outward, as at f, and formed on its inner side with a tubular loop-engaging post c ,having a iiange, an inward-extending catch b on the extremity of the outer member of the clasp to engage the said post-flange by a torsional strain,the washer m, having a notch m to register with the projection f, and the screw CZ, substantially as set forth.
